Their products meet international standards, giving you peace of mind and helping you stay compliant with local and global requirements.

You see 48V as the industry standard for telecom battery banks for several technical reasons. Historically, telecom systems used the earth as a return path. This required a negative power supply to reduce ground noise interference. The -48V standard remains because it protects cables from corrosion and increases system reliability.
Here is a quick look at why 48V is the preferred choice:
Reason | Explanation |
|---|---|
Safety considerations | 48V is a safe low voltage, meeting most safety regulations. |
Historical compatibility | 48V works with existing telecom systems worldwide. |
Reduced signal loss | 48V allows low signal loss over long distances. |
Corrosion prevention | Negative polarity helps prevent cable corrosion and extends system life. |
Voltages above 48V can be dangerous. Lower voltages need thicker wires, which increases costs and causes voltage drop losses. The negative polarity of 48V also reduces ground noise. You benefit from a standard that balances safety, efficiency, and compatibility.
You have several battery options for telecom applications. The most common types include lithium-ion, wet cell VLA, VRLA, and pure lead. Each type offers different lifespans and maintenance needs.
Battery Type | Lifespan (Years) | Maintenance Frequency |
|---|---|---|
Lithium-Ion | 15-20 | Once a year |
Wet Cell VLA & 20-year VRLA | Up to 15 | Four times a year (quarterly) |
Next Gen Pure Lead | 16 | Every 8 years |
Pure Lead | 5-7 | Every 5 years |
VRLA | 3-5 | Every 3-4 years |

You can choose lithium-ion batteries for long life and low maintenance. VRLA batteries offer lower upfront costs but need more frequent checks. ESTEL provides advanced battery storage solutions that support both lithium-ion and VRLA options. Their cabinets protect your battery investment with features like anti-corrosion coatings and climate control.
